Historical AttributesA note by Dr. Lewis on file card reads as follows: "The wide flange (body support) of the 'continental model' is not present on this one; simply a horizontal bar from post to tube, and is perhaps somewhat later. No accessories whatever but a blank form filled in ink by the maker for enlargements obtained 'avec une distance visuelle de 250 m m.' for no. 7914. Visiting card of Dr. J. Collins Warren, 58 Beacon St in box cover. Dr. Warren is thus the donor. Price list (now framed 'E. Hartnack & Cie Succrs de G. OBERHAEUSER' no date. No. 2 Vérick objective (special pupil of Hartnack's) has been supplied from 143 (discarded) and screw for mirror."
